Patty added the values of the expressions 2x3x11 and 2x3x10 to find the volume of the composite figure. Describe her error. What is the correct volume of the composite figure? For people with the same math books: Chapter 11 Lesson 11 Page 509

Answer 1

She added 8 cm and 3 cm.

Explanation:

The correct dimensions would be ( 2 x 3 x 8 ) + ( 2 x 3 x 10 ) . So the answer would be 108 cubic units.

Answer 2

her mistake is that shes not supposed to add shes first supposed to multiply each expression (2*3*11) and multiply (2*3*10) and then subtract 230 from 253
